Abstract:

Paleolake Hadar was an expansive lake in the lower Awash Valley of Ethiopia’s Afar Depression that existed periodically through the Late Pliocene. The sedimentary deposits from this ancient lake (Hadar Formation) have broad importance because a significant number of hominin fossils have been recovered from the formation. Samples of the Hadar Formation lacustrine sequence were collected from sediment cores extracted as part of the Hominin Sites and Paleolakes Drilling Project (HSPDP). A paleoecological study of the HSPDP Northern Awash (Hadar Formation) material has unearthed three novel species of Bacillariophyta (diatoms) from diatomites that appear periodically in the cores. The Hadar Formation assemblage represents a newly revealed excerpt from the evolutionary history of freshwater diatoms in East Africa during the Piacenᴢian age (2.59–3.60 Ma). The HSPDP Northern Awash diatom species are compared to previously reported diatoms from Pliocene outcrops, modern and fossil core material from Lake Malawi, and extant species. Here we describe two new species of Aulacoseira and one of Lindavia. Taxonomic treatment of two diatom varieties reported by previous researchers as Melosira are transferred into Aulacoseira herein.

Abstract:

Salmonella is a pathogen transmitted by foods and it is one of the most important target bacteria in food irradiation studies. Few works were carried out on the effectiveness of gamma radiation against biofilms formed by this bacterium. Salmonella can form a biofilm on different material surfaces. The physicochemical properties of surfaces and environmental factors influence the adhesion of this pathogen. The present study investigated the effect of gamma radiation (1 and 2 kGy) and temperature (28°C and 37°C) on the development of Salmonella Hadar biofilm on polyvinyl chloride (PVC), glass, cellophane paper (CELLO), and polystyrene (POLY). The obtained results indicated that biofilm production is surface and temperature dependent. In addition, biofilm formation decreased significantly after gamma irradiation at either 1 or 2 kGy doses. However, the agfD and adrA genes expression did not demonstrate significant decrease. This work highlighted that gamma radiation treatment could reduce the biofilm formation of Salmonella enterica serovar Hadar on different food contact surfaces.

Abstract:

Au Sultanat d’Oman, les fluctuations climatiques quaternaires sont caractérisées par une alternance entre périodes humides et arides. Aujourd’hui, le pays est principalement composé d’étendues désertiques et le peuplement se concentre traditionnellement dans des oasis alimentées artificiellement en eau. Cette thèse propose de reconstituer les variations hydro-climatiques de la fin du Quaternaire dans les piémonts de la chaîne du Jebel Hajar afin de mieux comprendre les potentialités des milieux de piémonts durant les périodes humides du Pléistocène et de l’Holocène et de suivre la mise en place de l’aridité depuis la fin de l’Optimum climatique holocène. A ces fins, elle mobilise une analyse pluridisciplinaire sur les archives fluviales continentales, la sédimentation littorale, et les sites archéologiques, dans quatre secteurs représentatifs des piémonts : Bat/al-Arid, Salut, Adam et Quriyat. Les données géomorphologiques et hydro-climatiques obtenues sont comparées à la répartition des sites archéologiques, aux stratégies de subsistance à chaque période archéologique et au mode d’acquisition de l’eau. Les résultats attestent d’un emboîtement des formes alluviales héritées au cours du Pléistocène et de l’Holocène, de la réduction des écoulements de surface à partir de 5 840 – 5 610 cal. BP, de la concentration progressive des sites archéologiques de l’âge du Bronze ancien vers des espaces hydrologiquement favorisés, d’une optimisation progressive de ces espaces dans les parties hautes du piémont et d’une forte mobilité de la ligne de rivage dans la plaine côtière de Quriyat à l’Holocène moyen et récent
In Oman, Quaternary climatic fluctuations are characterised by wet and dry periods. Today, desert landscapes prevail in Oman and traditional settlements mainly consist of artificially water-supplied oases. This work exposes the hydro-climatic variations at the end of the Quaternary in the foothills of the Jebel Hajar in order to (1) better understand the various environmental potential of the foothills during the wet periods of the Pleistocene and the Holocene and (2) reconstruct the onset of aridity since the end of the Holocene Pluvial Phase. To do so, multidisciplinary analyses are conducted on fluvial archives, coastal sedimentation and archaeological site’s distribution and nature, in four areas of the Jebel Hajar foothills : Bat/al-Arid, Salut, Adam and Quriyat. The geomorphological and hydro-climatic data are compared with the distribution of archaeological sites, subsistence strategies in each archaeological period and water distribution/ acquisition. The results obtained attest a nesting of the alluvial forms during the Pleistocene, the reduction of surface runoffs as early as 5,840 - 5,610 cal. BP, the gradual concentration of the archaeological sites towards hydrologically favoured areas, a progressive optimisation of these spaces in the upper parts of the foothills and a high mobility of the shoreline in the coastal plain of Quriyat during the Mid-Late Holocene

Abstract:

abstract: East African extensional basins have played a crucial role in revealing the evolution and characteristics of the early stages of continental rifting and for providing the geological context of hominin evolution and innovation. The numerous volcanic eruptions, rapid sedimentation and burial, and subsequent exposure through faulting and erosion, provide excellent conditions for the preservation of tectonic history, paleoenvironment data, and vertebrate fossils. The reconstruction of depositional environments and provision of geochronologic frameworks for hominin sites have been largely provided by geologic investigations in conjunction with paleontological studies, like the Ledi-Geraru Research Project (LGRP). High-resolution paleoclimate records that can be directly linked to hominin fossil outcrops have been developed by the Hominin Sites and Paleolakes Drilling Project (HSPDP) which collected sedimentary-paleolake cores at or near key hominin fossil sites. Two chapters of this dissertation are a result of research associated with the HSPDP. For HSPDP, I establish a tephrostratigraphic framework for the drill cores from the Northern Awash (Afar, Ethiopia) and Baringo-Tugen Hills-Barsemoi (Kenya) HSPDP sites. I characterize and fingerprint tephra through glass shard and feldspar phenocryst geochemistry. From tephra geochemical analyses, I establish chronostratigraphic ties between the HSPDP cores’ high-resolution paleoclimate records to outcrop stratigraphy which are associated with hominin fossils sites. Three chapters of this dissertation are a result of field work with the LGRP. I report new geological investigations (stratigraphic, tectonic, and volcanic) of two previously unmapped regions from the eastern Ledi-Geraru (ELG), Asboli and Markaytoli. Building upon this research I present interpretations from tephra analyses, detailed stratigraphic analyses, and geologic mapping, of the Pleistocene (~2.6 to < 2.45 Ma) basin history for the LGRP. My work with the LGRP helps to reconstruct a more complete Early Pleistocene depositional and geologic history of the lower Awash Valley. Overall, this dissertation contributes to the reconstruction of hominin paleoenvironments and the geochronological framework of the Pliocene and Pleistocene faunal/hominin records. It further contributes to rift basin history in East Africa by elaborating the later structural and stratigraphic history of the lower Awash region.

Abstract:

Reception history provides examples of how characters in Old Testament narratives are interpreted in the New Testament, post-biblical Judaism, and Islam. The examples provided are drawn from those discussed in previous chapters and include Abraham, Isaac, Hagar, Ishmael, Ruth, Boaz, and Orpah. Various communities of faith have interpreted their lives in light of these canonical characters. Historically these communities of faith made the OT narratives not only formative for their identity, but often the stories became classical texts for the larger communities in which they lived. The chapter concludes with the question of how modern, secular readings of these canonical characters and stories should proceed, given the increasing cultural distance between past and present.

Abstract:

Australopithecus afarensis is a fossil hominin species known from at least four East African Rift Valley sites ranging from northern Ethiopia in the north to northern Tanzania in the south and bridging the time period between approximately 3.6 and 3.0 million years ago (Ma). First identified in the late 1970s as the bipedal but craniodentally apelike rootstock from which later Australopithecus and Homo evolved (Johanson et al., 1978; Johanson and White, 1979), A. afarensis constituted the first substantial record of unequivocal human ancestors older than 3.0 million years (Myr). An array of more recently made discoveries have placed A. afarensis in a pivotal position in early hominin phylogeny, bracketed in time between, on the one hand, two temporally successive species, A. anamensis and Ardipithecus ramidus, that jointly extend the hominin record back to 4.4 Ma (M. Leakey et al., 1995, 1998; White et al., 1994, 1995), and, on the other hand, the earliest strong (stratigraphic) evidence for hominin lineage diversification, with the first known records of A. africanus (ca. 2.7 Ma) in southern Africa, and of A. aethiopicus (ca. 2.7 Ma) and A. garhi (2.5 Ma) in eastern Africa (Walker et al., 1986; Asfaw et al., 1999).2 The task of sorting out the relationships among all of these species hinges on the interpretation of A. afarensis itself, from its alpha taxonomy and phylogenetic role to its pattern of evolution over time. A prerequisite to achieving this goal is a more complete knowledge of the A. afarensis fossil record, narrowing gaps in our knowledge of anatomy and variation, as well as of distributions in space and time. On sample size alone, A. afarensis is the best-known hominin species in the eastern African fossil record. The vast majority of fossils in the A. afarensis hypodigm, some 360 specimens, or approximately 90% of the total, have been recovered at the Hadar site, from the 200+ meter sequence of silts, sands, and clays that comprise the Hadar Formation, which is exposed along the drainages of the Awash River in the Afar Depression of northern Ethiopia (Johanson et al., 1982a; Kimbel et al., 1994).
